Hi @sandeep, After a while of testing I realized that the MPM Event that comes standard in its installation script does not work well for servers with high traffic.
When Nginx overloads Apache, it ends with the message Graceful Restart, but it is unable to finish the restart and the Webserver is blocked.
The solution I found was to use MPM_Prefork, but as your script compiles MPM_Event into the apache executable, I had to insert --enable-mpms-shared=all for apache to compile all MPMs and make them available for selection at httpd.conf .
For now it has been running well with my high traffic clients, and Apache has stopped crashing.
I left my tip for you to include this MPM configuration in your standard apache installation script in the next versions.
if there is an update with clamd and service file you need to run this again when high load is occurring, we're already started to debugging it but not found any solution to it, So for temporary fix we changed the clamd service (via the fix script) to run foreground to resolve the cpu load.
